LINCOLN V. JOHNSON AND FREDERICK J. FISHER, OF SAN FRANCISCO,CALIFORNIA.

CONTAINER-STOPPER.

Specification of Letters Patent.

Patented Mar. 26, 1915..

Application filed April 2, 1917. Serial No. 159,126.

To all whom it may concern Be it known that we, Lmoonr V. J oHN- SON andFREDERICK J. FISHER,C1131Z6I1S of the 7 United States, andresidents ofthe city and county of San Francisco, State of California, have made anew and useful inventionto wit, Improvements in Container-Stoppers; andwe hereby declare the following to be a full, clear, concise, and exactdescription of the same.

The objects of this invention are to make a device of this characterthat is simple in construction, durable in nature and beneficial to thepublic.

Another object is to provide a container that is held sealed by theinclos'ed contents, thereby insuring a positive preventing of leakage.

A further object is to make a stopper that will hold the inclosedcontents intact when placed in any position.

In the specification and the annexed drawing, the invention isillustrated in the form considered by us to be the best, but it is to beunderstood that the invention is not limited to such form, as it may beembodied in other forms, and it is also to be understood that in and bythe claims following the description it is desired to cover theinvention in whatever form it may be embodied.

In the drawings:

Figure 1 shows a container partially in section with the device appliedtherein.

Fig. 2 is a view illustratingthe means of opening the stopper to allowflow.

Fig. 3 is a sectional view of a stopper.

Fig. 4 is a view of the stationary member.

Fig. 5 show the manner of inserting the device into a container.

Fig. 6 is the common form of opener used.

As illustrated in the accompanying sheet of drawing, the container,designated by the numeral 1, is shown having the neck or throat 2thereon with the stopper, generally designated as 3, secured therein. Itis to be understood that the invention is not confined to the shape ofthe container shown, as by enlarging or reducing the size of the deviceit can be pplied to any vessel having an extended outlet.

The topper 4 and the projections thereon are unitary in construction,and it has been found that to make a serviceable device, capable ofbeing subjected to long, hard usage, that rubber with the sulfur blossomremoved is a very dependable material, but other materials can be used.

Rubber as here defined consists of either caoutchouc, gutta percha orindia rubber, or by any other of the titles that this elastic, resilientsubstance comes under.

The stopper 3 consists of the fiat resilient member 4, with the spud orlug 5 formed on the lower face thereof approximately the same diameteras the inner outlet 7 of the container throat 2, where it joins theshoulder 8 of the container 1. On the top face 9 opposite the side 6 ofthe member 4 is a resilient projection 10 preferably formed of the samematerial as the stopper 4 extending at right angles thereto and of lessdiameter than the plug 5.. The free end of the projection 10 terminatesand is secured in the piece 14.

The bridge member 14 is made of a material that is not susceptible tothe deleterious effects of acids or alkalis. The member as shown in Fig.4 consists of a flat wedge-shaped piece of material 14 having the hole16 bored therein and the section between the hole 16 and the wide top 17of the wedge, split, as shown at 18. The function of this slot 18 is,that when the resilient member 10 is secured in the hole 16 of the piece14 and the device 3 forced down into the throat of a container, as inFig. 5, the outward draft of the throat 2 will gradually impedeprogression or the member 14 and that by using greater force behind the1nember 14 at this point, the two sides of the wedge will partiallyclose and bind the member 14 in position in the neck. As the member 15assumes a permanent position in the neck 3, the hole 16 will hrve becomesmaller, and in turn exercised a tighter grip on the container member10.

The member 4 after the piece 5 has become fixed, assumes a position asindicated in Fig. 5. The sides of the piece 4 overlap the lug 5 forcingthe stopper 3 into a container, will bend upward around the smallerprojection 10. When the member 4 enters the interior of the bottle itreadily expands to a flat normal position and when downward pressure isreleased, is pulled upward by the elastic elongated projection 10 to bestopped by the shoulders of the outlet 7.

The member 4 cannot be drawn up through V the container throat 2 becauseof the lug 5 that prevents any downward bend, to the extent of allowingthe member 4 to be made small enough to allow it to go back up throughthe throat. The thickness of the piece 4 added to each side of thediameter of the lug 5 is of greater width than the internal diameter ofthe throat 2 and it is this fact that prevents the removal of thestopper.

This stopper is commercially valuable as a means for sealing a containerwithout any danger of the seal being broken and the contents allowed toescape.

For pouring contents from the container, any means 'for depressing thepiece l to break the seal can be used.- By way of illustration, Fig. 6shows the means 25 we employ, but a match or a Wire could be used in anemergency. This depressor 25 can be left in the container without dangerof falling out When the container is inverted.

Having thus described our invention what we claim and desire to secureby Letters Patent is: e

1. In combination with the throat of a container, of a rigid means fixedtherein; a

stopper engaging the inner outlet of said throat, and resilient meansintegral with said stopper connecting said stopper and said rigid meansfor holding said stopper in engagement. Y n c 2. In combination with thethroat of a container having a rigid means secured therein, of a stoppercovering the inner outlet of said throat; elastic means integralwithsaid stopper connected to said rigidmeans; and an elastic projectionon the side of the stopper opposite the elastic means.

3. 111 combination with the throat of a container having a rigid meanssecured therein, of a stopper covering theinner outlet of said throat;elastic means integral with said stopper connected to said rigidcontainer having a rigid means secured therein of a stopper covering theinner outlet of said throat; resilient1means-integral with said stopperconnected to said rigid means; and means for depressing the stopper 6.In combination with thethroat of a container having a rigid means"secured therein of a rubber stopper covering the inner outlet of saidthroat; and rubber means 7 connecting said rigid means and stopper,integral with said stopper, 7

7. In combination with a co ntainerhaving a throat; a transverse bridgefixed in said throat; and a stopper closing said throat and having anintegral resilient ex tension engaging said bridge;

' 8. In combination with the throat: of a container having a rigid meanssecured therein of a rubber stopper covering the inner outlet of saidthroat; rubber means integral with said rubber stopper connected. 0 tosaid rigid means aind'means fordepressing the stopper. 1

9. Incombination with a container having a throat a transverse bridgefixed in said throat; and a rubberstopper closing. said throat andhaving an integral rubber extension engaging said bridge. w In testimonywhereof, we have hereunto set our hands at San Francisco, California,this 27th day oil/larch, 1917.-
